For 4.4.2, an updated guide is available here

For real GPe devices (not ones with a GPe ROM added on it after the purchase), NO code is needed, simply skip to "3. Unlock"

1- Register to Motorola website

2- get your Device ID
  • Put your device in fastboot mode (power off, then press the power and volume down buttons simultaneously).
  • On your desktop, open a command prompt or terminal, and go to the directory where you installed the Android SDK tools (or make sure fastboot is in your $PATH)
  • At the prompt, type
$ fastboot oem get_unlock_data
  • The returned string will be used to retrieve your unlock key.
Example: On a Windows Desktop, the returned string format would be
$ fastboot oem get_unlock_data
 (bootloader) 0A40040192024205#4C4D3556313230
 (bootloader) 30373731363031303332323239#BD00
 (bootloader) 8A672BA4746C2CE02328A2AC0C39F95
 (bootloader) 1A3E5#1F53280002000000000000000
 (bootloader) 0000000
On a Mac OS Desktop, the returned string format would be
Paste together the 5 lines of output into one continuous string without (bootloader) or ‘INFO’ or white spaces. Your string needs to look like this:
3- Unlock
  • Check if your device can be unlocked by pasting this string in the pecific field on the Motorola website, and clicking “Can my device be unlocked?”
  • NOTE: If your device is unlockable, a "REQUEST UNLOCK KEY" button will now appear at the bottom of that page.
  • after you got the code type the following :
    fastboot oem unlock <code>
    or for GPe devices :
    fastboot oem unlock
    and wait your device to reboot !

4- Enjoy

5- to relock, (pointless, isn't it?)
First you'll need a stock firmware for your specific device [make sure the device number is the right one at least...]
Then follow these steps:
  1. Open the zip
  2. Find 'flashfile.xml'
  3. Make sure to check integrity of EACH img/bin files in the stock firmware zip before proceeding (to do that, look at the flashfile.xml)
        <step MD5="daae9a555a3789558ee44f9e1fddc8c5" filename="gpt.bin" operation="flash" partition="partition"/>
    check that gpt.bin MD5 is really daae9a555a3789558ee44f9e1fddc8c5 and has not been corrupted during download/unpacking
  4. Prepare your device (boot to fastboot) and start relocking:
    fastboot oem lock begin
  5. Flash in the order:
    mfastboot flash partition gpt.bin
    mfastboot flash motoboot motoboot.img
    mfastboot flash logo logo.bin
    mfastboot flash boot boot.img
    mfastboot flash recovery recovery.img
    mfastboot.exe flash system system.img_sparsechunk.0 // note that you may have more or less sparsechunks, FLASH THEM ALL
    mfastboot.exe flash system system.img_sparsechunk.1 // alternatively the files could be named system.img_sparsechunk[1-3] instead
    mfastboot.exe flash system system.img_sparsechunk.2
    mfastboot.exe flash system system.img_sparsechunk.3
    mfastboot flash modem NON-HLOS.bin
    mfastboot erase modemst1 
    mfastboot erase modemst2 
    mfastboot flash fsg fsg.mbn
    mfastboot erase cache
    mfastboot erase userdata
  6. Finish relocking:
    mfastboot oem lock
  7. Done!
